SPECIFICATION forming part of Letters Patent No. 459,312, datedSeptember 8, 1891.

Application filed August 28, 1890.

To all whom it may concern.-

Be it known that I, J'OHAFI GOTTLIEB EMIL SAUER, a subject of the Kingof Prussia, German Empire, residing at Berlin, Germany, have inventedcertain new and useful Improvements in IVriting and Drawing Tables; andI declare the following to bea full, clear, and exact description of thesame.

The ordinary writing and drawing tables present this disadvantage, thatthe table-leaf is either permanently fastened in the proper position andthe table as a whole can serve for but one particular purpose, or if thetablc-leaf is movably supported, then this suspension is uncomfortableand inconvenient for proper work.

The present invention has for its object the provision of a movablehorizontally-laid table-leaf which is light and can be adjusted at aconvenient slant for use while in a sitting position. This object isattained by certain operating mechanism, by means of which thetable-leaf is raised and securely fastened in that position.

In the accompanying drawings,'Figures I and II show cross-sections ofthe table in two positions of use. Fig. III is a plan view with thetable-leaf removed. Figs. IV and V show a modification. Figs.VI and VIIshow a modification.

At each side of the table-leaf A, Fig. 1, are bell-crank levers fastenedto a common shaft, the rounded horizontal arms a of which lie againstthe table-leaf, or preferably against the inlaid plate I). The arm a ofone of these bell-crank levers is hinged to the connectingrod B, whichextends parallel with the side of the table-drawer C, Fig. III, and hasa detent-pin to lock in the perforated plate g, and ends in a knob orpull d. The perforated plate g is fastened to the face-panel c, and hasa tongue 6 extending downward to the platespring f. The tongue 6 iseye-shaped and holds up the plate-spring f, fastened to the rod B, sothat the former is drawn by the latter toward the apertured plate g. Bymeans of this arrangement the table-leaf can be placed in any desiredoblique position, when the detent-pin of the rod B, after the rod hasbeen drawn forward to the desired point, snaps into the correspondinghole in the plate g, and thereby locks the rod B in place. The

suspension of the table-leaf .A is effected by the use of the knob d.The rod B is pressed down, and thereby the detent-pin on the plate g isloosened by the action of the spring f, so that the rod B can moveforward freely. The arms a a are thus brought from the position shown inFig. I to the position of Fig. II, and

so that the leaf A is supported in a slanting position by the hingesfastened to the facepanel of the table.

I can use the bell-crank levers a a? in the ordinary way, or I may useeccentric disks fastened upon the shaft.

The knob-pull d of the connecting-rod or draw-link B lies near at handon the rod, so that the person working at the table does not have toturn away to push the same.

Instead of the entire table-leaf being raised obliquely, it may beadvantageous to raise only a part of the same, as shown in Figs. IV andV. The mechanism for effecting the oblique raising of the movable leafof the table is then the same as that before described, yet themodification has this advantage that a part of the table-leaf remainshorizontal and may serve as a support for any articles lying thereonwithout the same being disturbed by the slanting position of the part A.The table A then serves, for example, as a drawingboard, so that aperson seated at the same can, if raised sufficiently high,use hisdrawing-instruments with facility; but for a larger Writing or worktable-as a school-desk, for example-the separation of the movable part Afrom the table-leaf A is advantageous, and in this event each side ofthe table can have its own particular raised leaf, so that more than oneperson may be able to work at the 0 same time.

The same device may be used, also, to turn at the same time two oppositetable-leaves, as shown. in Figs. VI and VII, whereby by their rise anequilateral plane surface is provided, which serves as a support for alamp, an inkwell, &c. For this purpose the table-top is made in threeparts, and consists of the small middle leaf A hinged to the two broadside leaves A The two side leaves A are not in this case, as they werein Figs. I to IV, connected with the side panel of the table by hinges,but carry on their forward ends angled locking-arms 72 whose horizontalarms can slide upward on the table-braces 2 provided for their guidance,as well as forward and backward. The lever a a fastened to theconnecting-rod l3, lies now, as before, with its arm a under the middlepart A but which now, lying in the same way, has a clownwa'rdly-curvedarm a so that by a full forward pull of the rod B the arm a lies in ahorizontal position and forms a horizontal prop for the middle leaf A ofthe desk-top. This top leaf A is provided with upright guide-rods, sothat by the turning of the lever a a said top leaf is raisedperpendicularly. By the elevation of the top leaf A the side leaves Aare also raised, and their front edges are held by the lockingangle-irons h sliding on the frame-braces i, so that the ele-
